Title (EN) GOLF BALL COVER COMPOSITIONS AND METHOD OF MAKING SAME
(FR) COMPOSITIONS DE REVETEMENT DE BALLE DE GOLF ET LEUR PROCEDE DE PRODUCTION
Abstract:
(EN) A process for forming a golf ball cover composition, which process comprises: a) forming a polymer comprising (1) a first monomeric component comprising an olefinic monomer having from 2 to 8 carbon atoms; (2) a second monomeric component comprising an unsaturated carboxylic acid based acrylate class ester having from 4 to 22 carbon atoms; and (3) an optional third monomeric component comprising at least one monomer selected from the group consisting of carbon monoxide, sulfur dioxide, an anhydride monomer, an unsaturated monocarboxylic acid, an olefin having from 2 to 8 carbon atoms, and a vinyl ester or vinyl ether of an alkyl acid having from 4 to 21 carbon atoms; b) applying a sufficient amount of heat to the polymer to convert it to a substantially molten state; c) adding an inorganic metal base to the molten polymer to form a mixture; and d) saponifying the mixture to form a polymer salt particularly adapted for forming improved golf ball covers.
(FR) Procédé de production d'une composition de revêtement de balle de golf, consistant à: a) former un polymère constitué 1) d'un premier élément monomère comprenant un monomère oléfinique comportant de 2 à 8 atomes de carbone; 2) d'un deuxième élément monomère comprenant un ester classe acrylate à base d'acide carboxylique insaturé comportant de 4 à 22 atomes de carbone; et 3) éventuellement d'un troisième élément monomère comprenant au moins un monomère choisi parmi monoxyde de carbone, dioxyde de soufre, monomère anhydride, acide monocarboxylique insaturé, oléfine comportant de 2 à 8 atomes de carbone, et ester de vinyle ou éther de vinyle d'un acide alkylé comportant de 4 à 21 atomes de carbone; b) à appliquer une quantité de chaleur suffisante sur le polymère pour l'amener à un état sensiblement fondu; c) à ajouter une base métallique inorganique au polymère fondu pour former un mélange; et d) à saponifier le mélange pour former un sel de polymère particulièrement adapté à la fabrication de revêtements de balles de golf améliorés.
